Description
Technical field
The utility model relates to a kind of liquid crystal indicator, particularly a kind of liquid crystal injecting port is positioned at the liquid crystal indicator on same one side of terminals, when carrying out sealing compound when manually being coated with operation, can be coated with along glass surface, with the instability of improving artificial coating and avoid sealing compound to overflow the pollution glass baseplate surface, cause subsequent module housing packing problem.
Background technology
As shown in Figure 1, traditional liquid crystal indicator 1 generally comprises a pair of glass substrate 10, and is bonding with adhesive linkage (the frame glue) 12 that puts on along the edge therebetween each other, and, between glass substrate 10, evenly apply interval dose bead (not shown).Interval dose bead and adhesive linkage (frame glue) 12 forms LCD ejection gap 14, and its thickness (about 1 micron to 5 microns) is corresponding to the gross thickness of interval dose bead and adhesive linkage (frame glue) 12.Via the liquid crystal injecting port 16 of position in adhesive linkage (frame glue) 12 liquid crystal material is injected LCD ejection gap 14 subsequently.This one side to glass substrate 10 is terminals 18, uses the liquid crystal injecting port 16 of immersion liquid crystal injection mode at present, is the corresponding limit that is positioned at terminals 18.
Fig. 2 A uses the LCD ejection device for explanation liquid crystal material is injected the figure of liquid crystal board, at this, " liquid crystal board " speech means in the LCD ejection gap 14 the not plate of filling liquid crystal material, that is, and the plate of filling liquid crystal material not between the glass substrate 10 of first figure.LCD ejection device 20 comprises the seal groove 26 of regulating liquid crystal board 22 and liquid crystal material 24 simultaneously, and be used to adjust the pressure regulating mechanism 28 of seal groove 26 internal pressures, pressure regulating mechanism 28 comprises pilot piping 281,282, inside and outside in order to communication seals groove 26, be positioned at the valve 283 and 284 and be positioned at the vacuum pump 285 of the end of pilot piping 281 in the middle of pilot piping 281 and 282.Liquid crystal board 22 is supported by the supporting mechanism (not shown), and to move in vertical direction, liquid crystal material 24 is stored in the carriage 262, and this carriage 262 is positioned on the basal surface of seal groove 26.
Use flow process that the LCD ejection device injects liquid crystal material liquid crystal board as described in the following step:
(1) at first, shown in Fig. 2 A, the position of liquid crystal board 22 does not contact with liquid crystal material 24.
(2) close down open valve 283 in valve 284, start vacuum pump 285 subsequently, so that seal groove 26 is vacuumized.
(3) in a single day reach predetermined vacuum level, the support mechanism (not shown) of then asking for an advance on one's pay reduces liquid crystal board 22, makes the liquid crystal injecting port 16 that is arranged in liquid crystal board 22 be dipped in liquid crystal material 24, shown in Fig. 2 B.
(4) subsequently in 284 times shut-off valves 283 of open valve, so that surrounding air is imported in the seal groove 26.At this moment, will be applied in atmospheric pressure in the environment on liquid crystal material 24 surface; Press high liquid crystal material 24, and insert in the LCD ejection gap 14, shown in arrow among the 2nd B figure.Certainly, capillarity is also contributed to some extent to the filling power of stowing operation.
After the liquid crystal injection is finished, next be sealing compound to be made coating and cure process along glass substrate 10 edges with artificial coating method, be as sealing compound, shown in the 3rd A figure at present with UV glue.The follow-up glass substrate 10 surperficial Polarizers that carry out again attach and the module assembling.
Tradition is used the liquid crystal injecting port 16 of immersion liquid crystal injection mode, is the corresponding limit that is positioned at terminals 18, has following shortcoming and produces:
(1) when carrying out the coating of liquid crystal injecting port 16 sealing compounds with the manual mode of operation, the bad situation of coating is caused, shown in Fig. 3 B in the coating position at wayward glass substrate 10 edges.
(2) coating process often has sealing compound to overflow situation, because sealing compound can pollute glass substrate 10 surfaces, causes follow-up Polarizer to attach bad problem and produces, so need handle glass substrate 10 surperficial culls with scraper before Polarizer attaches.
(3) when subsequent technique is done the combination of module housing,, necessarily require the outstanding height of sealing compound less than 0.6 millimeter, shown in the 3rd C figure for cooperating the housing assembly error.Because the artificial wayward height of coating method is in specification value, so often need the action of striking off or repairing, to reach housing combination requirement, this action causes product that integrity problem is arranged easily, makes the liquid crystal possibility that leaks outside.
